The most likely issue is the hi-limit switch has tripped. Some hi-limits are customer accessable
sorry, most are located internally. They are in place to shut the unit down if it over heats. verify the condenser is clean and its internal area is clear. locating the hi-limit (if not at the rear) can be rather involved.
Thank you for the reply.
Do you mean the hi-limit switch for the heater? I checked this and it is not tripped.
The condenser is clean and the internal area is clean also.
Ok if the high limit is good the only other power supply to the display would be the
door switch is it making contact ?
